Product Description
Specifications
DQT-502 is a type of blend polyether polyols, which is specially researched for rigid PUF to produce thermal insulation pipes.It is widely used in steam pipes, liquefied nature gas running pipes, oil pipes and other fields. The characteristics are as follows:
1. good flowability, by regulating formula to suit different pipe diameters.
2. high temperature-resistance performance, long standing in 150°C
3.excellent low temperature dimensional stability
